ELECTRIC BELT.

SPECIFICATION forming part of Letters Patent No. 366,058, dated July 5,1887.

Application filed January 24, 1837. Serial No. 225,331. (No model.)

T all whom, it may concern:

Be itknown that we, ROBERT E. WILLIAMs, of Dallas, in the county ofDallas and State of Texas, and TURNER G. HAMMER, of New Orleans, in theparish of Orleans and State of Louisiana, have invented certain new anduseful Improvementsin Electric Belts; and we do hereby declare that thefollowing is a full, clear, and exact descriptionof the invention,

io which will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,which form a part of this specification, and in which- Figure 1 is aperspective View of the inner side of our improved electric belt. Fig. 2is a similar view of thc outer side of the belt,sho\v ing the beltopened to expose the elements or batteries. Figs. 3 and 4t are sectionalviews of one of the batteries, taken at right 'angles to each other.Fig. 5 is a perspective view ofthe parts of the battery separated. Fig.6 is a perspective view ofthe auxiliary band or belt. Fig. 7 is asimilar view of the end of the belt,

,25 showing the auxiliary belt attached to it; and

Fig. Sis a sectional view of one of the elecredes.

Similar numerals of reference indicate corre sponding parts in all thefigures. 3c Our invention has relation to that class of electric beltsin which a chain of batteries is inclosed in a belt having` -two polesor eleetrodes upon the inner side at the ends of the chain of batteries,and it consists in the improved construction and combination of parts ofsuch a belt, as hereinafter more fully described and claimed.

In the accompanying drawings,the numeral 1 indicates a strip of asuitable fabric having 4o its inner side coated with a non-conductingmaterial, and having its edges doubled over to form flaps 2, overlappingeach other. Tapes or bands 3 are secured to the upper overlapping flapand passed over theinner side of the belt formed by the strip, the endsof the tapes serving to secure the overlapping iiaps, and the portionupon the inner side of the belt serving to form loops for the receptionof a strip of material-such as annel or similar 5o material, ifdesired-for the purpose of avoiding the contact with the fabric of thebelt with the body. A chain of batteries, 4, isinclosed in the pocketformed by the flaps of the belt, and each battery consists of a thickzinc plate,

v5, having a perforation, 6, at its middle and perforations7 neartheends, diverginggrooves 8 extending froln the central perforation uponthe inner side of the plate, and of a piece of sponge or other absorbentmaterial, 9., and a thinner copper plate, l0. Thecoppcrplateis formedwith a long receptacle, 11, struck up at its middle, and a piece ofsponge, 12, or other absorbent, may be placed Within this rcceptacle,and the piece of absorbent material is placed between the two plates,and the plates are secured together by suitable threads or'cords, 13,passing through the perforations in the plates and through the absorbentfabric. One edge of the copper plate is formed with a wide lip, 14,which is doubled inward; and the doubled end of a copper wire, 15, issecured in the hook formed by this lip and has its converging endsinserted through the central pcrt'orationin the zinc plate, whereuponthe ends are spread to [it into the grooves in 75 the` inner face ot'the zi nc plate, the spread ends serving to retain the wires inposition. The zinc plate of the batteryat one end is formed with aclamping plate', 16, of zinc, and a doubled piece, 17, of copper wire isattached to this plate and has its other end bent to form a hook, 18,and the copper plate at the battery at the other ,end has a long wirehook, 19, attached to its hooked lip. The inner side of the belt isformed with perforations 20, through which the eyed shanks 2l of twopoles or electrodes, 22, project, and these electrodes are formed in theshape of buttons, having their convex sides forming a receptacle for asponge, 23, or other absorbent, the outer con- 9o vex side of theelectrodes having perforations 24. One of these electrodes is preferablycircular, while the other electrode is oval, the oval form enabling itto more conveniently be placed against the back; but the form of theelectrodes is, however, immaterial, being conformed to the place towhich they are to be applied. A chain, 25, may be attached to the end ofthe long hook at the end of the chain, and the electrode at that end maybe shifted IOC) into the farther perforations, when the chain may beattached to its eyed shank and con nected to the hook, thus enabling thesame chain to be used with belts of different lengths by simplyattaching the chain at the end hook. A pocket, 26, is formed at thecopper end of the belt, and the overlapping tiap of this pocket isformed with perforations 27 through which the wire 28, having aninsulating covering, may'pass into the pocket, the wire passing throughan aperture, 29, in the seam which separates the pocket from the longpocket for the batteries, and being secured to the hook at that end ofthe batteries. A piece, 30, of tape or string is secured to theoverlapping iiap of the small pocket, and' serves to secure theinsulated wire when the latter has been drawn suftieiently far out ofthe pocket. The other end of the insulated wire is attached to a chain,31, inclosed in a small band or belt, 32, of an insulating material, anda number of small hollow electrodes or buttons, 33, containing asuitable absorbent and having perforated faces, are secured to the chainwith their eyed shanks 34, the said eyes passing through suitableapertures, 35, in the belty or band. The end of the insulated wire isprovided with a snaphook, 36, or other suitable fastening, by means ofwhich it may be detachably secured to the end of the Chain in the'belt.

It will be seen that the batteries in the chain may absorb and retain aconsiderable quantity of acid, having the layer of absorbent fabricbetween the plates, and having, furthermore, the piece of absorbent inthe receptacle or cup formed in the copper plate, and the absorbentfilling of the electrodes will admit of the current ot' electricity fromthe belt being administered gently to the body without any stingingsensation, which is liable to be felt if the current is admitted throughdry electrodes.

'Ihe auxiliary belt or band may be used upon one of the limbs, and theinsulated wire may be drawn out of the pocket to the desired length,whereupon it may be secured by the piece of tape upon the pocket, thewire being inclosed in the small pocketwhen not in use.

Having thus described our invention, we claim and desire to secure byLetters Patent of the United States belt and fitting upon the hooks ofthe chain of batteries, as and for the purpose shown and` set forth.

2. In an electric belt, the combination of a zine plate havingperforations near its ends and a central perforation, and formed withdivergng grooves from the central perforation upon the inner side, acopper plate having perforations near its ends and formed with a longbulge in its inner side, forming a receptacle, and having a wide hookedlip at one edge, a piece of absorbent fabric secured between the platesby threads or cords passing through the perforations in the same, apiece of absorbent in `the receptacle in the copper plate, and a pieceof doubled wire having its doubled end held by the wide hook and havingits ends secured in the perforation of the zinc plate of the adjoiningbattery, having the ends spread to lit in the grooves in the zinc plate,as and for the purpose shown and set forth.

3. In an electric belt, the combination of a` belt formed withoverlapping lianges upon the outer side and having a'small pocket formedat one end, having perforations in the overlapping flange of the smallpocket, a piece of tape Aupon the overlapping flange of the pocket, a

chain of batteries in the main pocket ofthe belt, and an insulated wiresecured to one end of the chain of batteries and passing through theaperture in the row of stitches into the small pocket and through anaperture in the ange, having a snap-hook at its-end, as and for thepurpose shown and set forth."

` In testimony that we claim the foregoing as our own we have hereuntoaffixed our signatures in presence of two witnesses.
